The object on the call-site should remain to be an object (if it's not passed by reference), however the called function will receive a string. It works in PHP-5 and PHP-7.

Dmitry, I was talking about passing an object to a function, expecting a reference of a string: 'class X { function __toString() { return spl_object_hash($this); } } $x = new X; function foo(string &$x){} foo($x); var_dump($x);' Now what would this produce in Coercive STH is still an open question I guess as there is no implementation yet.
